MOOSE, WY — The status of Teton Park Road, Moose-Wilson Road, and Signal Mountain Summit Road within Grand Teton National Park has been changed from wheeled access to over snow access due to recent snow accumulation. The designated portions of these roads are now ready to accommodate winter recreational use and wheeled access is prohibited for the season.
Each year, Teton Park Road, Moose-Wilson Road, and Signal Mountain Summit Road are closed to public motor vehicle use beginning November 1. During the period of time that the roads remain free of snow, visitors are welcome to use the roadways for recreational activities such as walking, bicycling, and in-line skating.
Once snow begins to accumulate on the roadbeds, the status is changed to over snow access and approved winter season activities such as cross-country skiing, skate skiing, and snow-shoeing become possible. Snow bikes are not permitted on roads designated for over snow access. Snow bikes are allowed on all roadways open to motor vehicle use in Grand Teton National Park including the East Boundary and Gros Ventre roads as well as the plowed portions of Teton Park and Moose-Wilson roads.
This year, the 14-mile section of the Teton Park Road between the Taggart Lake Trailhead and Signal Mountain Lodge will be groomed approximately twice-weekly from mid-December to mid-March depending on snow and weather conditions. This year’s grooming is made possible through the support of Grand Teton National Park Foundation, Jackson Hole Nordic Alliance, and a Federal Highway Administration Recreational Trails Program grant managed by the State of Wyoming. Park visitors can call the park’s road condition line at 307-739-3682 for grooming updates.
Generally, pets are only permitted on park roadways open to motor vehicle use. However, pets are allowed on the over snow access portions of the Teton Park Road and Moose-Wilson Road by special exception. Pet owners are reminded that pets must be on a leash no longer than six feet and under physical restraint at all times. Pet owners are required to clean-up their pet's waste, and mutt mitt stations are provided for that purpose during winter.
Grassy Lake Road in the John D. Rockefeller, Jr. Memorial Parkway is closed for the season to wheeled vehicles and bicycles. The road opens to snowmobiling at the start of the Yellowstone Winter Use Season.
